Take waste water filter, remove it and measure the absorption of light and absorb the changes in relationships. Of the graph so it absorbs all of the material term 2.
The wastewater is filtered to remove the adsorbent and then measuring the absorbance and translated into a relationship graph of the adsorption isotherm of material 2.
The water filtered removing adsorbent out that measure absorbance and convert values in the form of a relationship . Graph of isotherm of absorbent material and a 2 .
